HENRY J. DANIEL, OF KENDAIIL, MONTANA.

EXTENSION STOVEPIPE LENGTH.

Application led October 24,- 1907.

To all whom it may concern:

Be it known that I,` HENRY J. DANIEL, citizen of the United States, residing at Kendall, in the county of Fergus and State of Montana, have invented certain new and useful Improvements in Extension Stovepipe Lengths, of which-the following is a specification.

This invention contemplates certain new and useful improvements in stovepipes, and relates particularly to an improved extension coupling therefor.

It is well known that the ordinary stovepipe has many disadvantages rominent among which is its incapability of being extended to compensate for a sagging of the pipe or a shifting of position thereof.

The object of this invention is an extension stovepipe coupling which may be adj usted to overcome the faults of the ordinary pipe and thus insure tight joints thereof.

With this and other objects in view which will more fully appear as the description proceeds, the invention consists in certain constructions and arrangements of parts that I shall hereinafter fully describe and then lpoint out the novel features in the appended claims.

For a full understanding of the invention and the merits thereof and to acquire a knowledge of the details of construction, reference is to be had to the following description and accompanying drawings, in

which Figure 1 is an elevation-of my improved stovepipe coupling. Fig. 2 is a vertical section thereof with the movable collar against the flared thimble, and` also showing said movable collar in dotted lines supporting the main section of pipe. Fig. 3 is a detail plan view lof the flared thimble. Fig. 4 is a similar view of the movable collar, and, Fig. 5 is a cross section showing a guide rod and its connections with the collar and the thimble.

Corresponding and like parts are referred to in the followinoP description and indicated in all the views of the drawings by the same reference characters.

My improved stovepipe coupling, embodies primarily a length of stovepipe l of any desired size, preferably slightly smallerthan the main pipe section 2 with which it is designed to connect at one end, and into which it is designed to be ushed so as to be substantially incased by t e second pipe as shown.

Specification of Letters Patent.

serial No. 399,069.

The pipe lis tightly encircled by a collar 3 which is mounted thereon for longitudinal movement and against which the end of the incasing pipe 2 is designed to abut. This collar is provided at diametrically opposite points with outwardly extending lugs 4 each formed with a threaded aperture 5 extending therethrough. To the other end of the pipe l a flared and relatively stationary thimble 6 is secured so as to ht over the end of an ordinary sized stovepipe to form a joint therewith. The thimble4 6 is provided with lugs 7 in alinement with those of the collar 3 and similarly formed except that the apertures thereof are not threaded.

Journaled at one end in the lugs 7 are threaded guide rods 8, about the same length as the pipe 2 and extending parallel thereto. These rods are designed to engage the threads of the openings 5 of the respective lugs 4 of the collar 3 and to regulate the position of said collar on the pipe 1, by being screwed in one direction or the other.

The rods 8 are preferably constructed near their ournal ends with finger grips 9 whereby they may be turned, each grip being formed with one or more openings 10 extending transversely therethrough and designed to accommodate a pin or spike which it may be necessary to employ to effect the screwing of the rods.

In the practical operation of my extension stovepipe, the length thereof may be increased or diminished between certain limits7 by screwing the threaded rods in one direction or the other. Such action adjusts the position of the collar 3 over which the end of the incasing pipe 2 fits and thereby regulates the extension.

In the case of the sagging of the stovepipe or the loosening of the joints thereof, if my extension length or coupling is used it is only necessary to screw the rods in the proper direction to raise the collar and the end of the pipe bearing against it, thus extending the pipe length to compensate for such sagging and to tighten such loose joints. Also my improved stovepipe obviously overcomes the necessity of taking down a stove pipe and recutting and reiitting it when a small shift of position is required.

From the above description in connection with the accompanying drawings, it will readily be seen that I have provided a simple, durable and efficient construction of stovepipe which obviates many of the disadvantages of the ordinary type and which may be easily and cheaply manufactured.

Having thus described the invention, what I claim is: f

1. A device of the character described,

comprising a length of stovepipe, a flaredr thimble, guide rods secured to the lugs ofthe flared lohimble and projecting through the apertures of the lugs on the collar, Aand means for holding the `movable collar rigidly to the guide rods at different points along their length.

2. A device of the character described, comprising a length of stovepipe, a thimble secured to one end of said stovepipe and formed with -outwardly extending lugs, said lugs being formed with apertures extending therethrough, a collar mounted for longitudinal movement on said stovepipe, said collar being provided with outwardly extending lugs formed with threaded apertures extending therethrough, said lugs being in alinement with those of the thimble, and threaded guide rods journaled in the apertures in the lugs of the thim'ble, said rods being designed to operatively engage the threads of the apertures of the movable collar as and for the purpose set forth.

3. A device of the character described,

'comprising a length of stovepipe provided at `one end with a flared thimble formed with outwardly extending lugs, a collar mounted for longitudinal movement on said stovepipe and provided with lugs in alinement with those of the flared thimble, said lugs "being formed with threadedy apertures extending therethrough and threaded guide rods journaled at one end i-n the lugs lof the flared thimble and provided near their journaled ends with inger grips formed with transversely extending holes therein., said guide rods being designed to voperatively engage the threads of the aperturesof the movable collar as and for the purpose set forth.

In testimony whereof I :aflix kmy signature in presence of two witnesses.
